T o all whom 'it 'may concern:

Be it known that I, MORITZ STEGER, a citi- Zen of the German Empire, and resident of 29 Ehrenfelderstrasse, Bochuni,= Germany,

,in Apparatus for Separating Particles of Liquid from Gases and Vapors, of which the Forl separating vfrom gases and vapors, finely divided but liquid substances such as tar, oil and the like, apparatus is in some cases used, which effects the separation by means of powerful mechanical action on the gas or vapor. The action referred to may be frictional, centrifuga-l or due to impact' or vapor being at the same time divided into separate streams by passing through perforated baiiles or sieves.

The present invention relates toapparatus of this type, and its object is to provide ap` cited are collectively produced, for the purcicncy. For this purpose the gas or vapor is passed lirst through a fixed sieve and then through a rotating sieve arranged behind ing to deflect t-he streams of gas or vapor and produce powerful frictional and centrifugal action. Any number of alternate fixedY and rotating sieves, may of course be used in succession.

Apparatus embodying this improvement Figure l is a vertical cross-section of the apparatus and Fig. 2 an elevation of part of one of the sieves, drawn to a larger scale.

The term gas will be used hereinafter in a general sense to include vaporous sub# stances.

Referring tothe drawing, the gas enters superposed, conical, perforated plates d. To facilitate the assemblage the casing is in part built up of separate \rings a1, a2, a3 etc.- The perforated plates d are arranged in the casing alternately with rotatable perforated plates e, which are fixed to a vertical axle having bearings f and p. Hydraulic seals g and stuffing-boxes g make gas-tight joints where the axle enters its bearings'. The axle has at its upper end a collar 1 resting on a ring of antiefriction balls s on a ball-race Within a hollow spindle t. To prevent the lifting of the axle by gas-pressure it is held down by a yoke t1. Balls may be interposed between the axle and yoke to reduce friction. A screw-threaded Sleeve u, with a handwheel fixed thereto, engages `the 'spindle z5 and enables the axle to be rvertically adjusted for the purpose of adjusting the distance of the rotatory plates c from the adjacentplates 0l.

The apex angle of the conical plates is approximately 120 degrees. With this angle the separated liquid flows freely down the surface of the plates al. The circumferential parts of the plates d form, in conjunction with the wall of the casing a, annular troughs which communicate with discharge pipes z'. The latter terminate, in separate compartments of a vessel Z, the partitions 7c between the said compartmentsbeing sealed at the bottom by liquid.

Fig. 2 shows a portion of a conical plate d pinges against the lug nand the particles of liquid carried by the gas are thrown forcibly outward in a tangential direction by impact with the lug. If the lugs are given a slight inclination, as shown inthe drawing, the gas exerts a turning ei'fort, as a turbine, the fixed plates d acting as guides and-the plates e as rotors. The pressure of the gas is in most cases .suiiicient to impart rapid rotationto the plates e, the resistance offered to this rotation being very slight.

The apparatus illustrated is suitable for use as a tar separator; For using it atl the same time as an ammonia washer, pipes 0 are joined to the rings a1, a2, af.3 etc., and water under pressure 1s introduced throughl these pipes into the chambers between the plates. If the' tar is rich in naphthalene the said pipes may be used for blowing through the apparatus.r

To enable an auxiliary blower, with nozzle to be used if necessary for imparting rotation to the plates e, the undermost plate e has a cylindrical flange y on which a series of varies y are formed, for example by bending out portions of the material. These vanes are staggered, so that the axle can be having quadrangular apertures m. Thev vertically moved, within limits, without interfering with the Idrive imparted by the blower.

What I claim is l. A device of the character described, comprising a casing, a series of inclosed perforated movable plates, a series of intervening-perforated fixed plates, and vanes projecting from the fixed plates.

2. A device of the character described, comprising a casing, a series of inclosed perforated movable plates, a series of intervening perforated fixed plates, and inclined integral vanes projecting from the fixed plates.

3. Apparatus for separating, from gases or vapors, particles of liquid such as tar, oil and the like, comprising a casing having inlet and eduction orifices, fixed perforated conical baffle plates in said casing and perforated rotary bafiie plates fixed to vertical axle and alternating with said fixed plates,

each of said fixed baffle plates being joinedto the wall of the casing to form therewith an annular trough substantially as described.

4. Apparatus for separating, from gases or vapors, particles of liquid such as tar, oil 'and the like, comprising a casing having inlet and eduction orifices, fixed perforated conical bafiie plates in said casing, and perforated rotatory baille plates fixed to vertical axle and alternating with said xed plates each of said fixed baille plates being joined to the wall of the casing to form therewith an annular trough and the annular trough being collectively in communication with a discharge receptacle, substantially as de* scribed.

5. Apparatus for separating, from gases or vapors, particles of liquid such as tar, oil

and the like, comprising a casing having inletand eduction orifices, fixed perforated bafiie plates in said casing, androtatory perforated baffle plates alternating with said fixed bafiie plates, the distance between the fixed plates and rotatory plates being adjustable from outside the casing, substantially as described.

6. Apparatus for separating, from gases or vapors, particles of liquid such as tar, oil and the like, comprising a casing havingv inlet and eduction orifices, fixed perforated I xed baffle plates, the distance between the' fixed plates and rotatory plates being adjustable from outside the casing, and the undermost rotatable baffle plate having a cylindrical flange on which vanes are formed in a position to receive the impact of a propelling jet issuing from a nozzle.
